Castrol Molub-AlloyOG 3710-0/00 (previously called Castrol Molub-Alloy 3710-0/00) is a heavy-duty lubricant formulated for open gear mill applications. It may be used in both raw and finish mill operations such as those found in coal, cement, copper and phosphate mills as well as in ball or rod mills. Formulated to address environmental concerns Castrol Molub-Alloy OG 3710-0/00 is free from lead, antimony, barium, bitumen and chlorinated solvents. The synthetic and petroleum oils used in Castrol Molub-Alloy OG 3710-0/00 are selected for their physical and chemical stability and for their exceptional serviceability over a wide temperature range. These fluids are compounded to flow readily in the film forming process, yet resist “squeeze out” and cling tenaciously even to gear teeth that mesh vertically. A proprietary blend of Castrol Molub-Alloy OG 3710-0/00 lubricating solids of selected grade and size distribution promote antiwear and load carrying properties beyond the capacity of conventional lubricants. The blend of synthetic and petroleum base fluids ensures excellent pumpability even at low temperatures. The high base oil viscosity assures sufficient film thickness at low speeds and high loads.
